[PATCH] D95460: [flang][driver] Add forced form flags and -ffixed-line-length

[Joachim Protze via Phabricator via cfe-commits]

protze.joachim added a comment.

Before this patch, clang would happily ignore a `-ffree-form` flag. With this patch, none of `-Wno-error=unknown-argument`, `-Wno-unknown-argument` , `-Qunused-arguments` help to avoid clang from exiting with

  error: unknown argument: '-ffree-form'

Why can't clang ignore these flags as any other unknown flags?

As a background: in the build system I'm dealing with, I cannot avoid that fortran flags are passed to the linking command. As C++ and fortran is involved, I prefer using clang++ as the linking command and explicitly link the fortran runtime library (at the moment gfortran, but in the future probably the flang runtime library)
